Abstract
Vindskruen er en vindrotor som utpreger seg ved at den roterer både når rotoraksen står vinkelrett på vinden (fig.1 og 2) og når den ligger i vindretningen (fig.3 og 4). Den fungerer med uendret effekt også i alle stillinger mellom vertikalstillingen (fig. 1 og 2) og horisontalstillingen (fig. 3 og 4) og vender alltid samme flater mot vinden uav-hengig av stillingen for rotoraksen (B). Rotorvingene har en noe kupolformet overflate (fig. 1 og 3). Disse faktorer har løst vanskelighetene med å gjøre en og sammen rotor effektiv både i lave vindhastigheter (fig. 1 og 2) og i storm (fig. 3 og 4). Rotoren består av to vinger som er vridd 180° skrueformet om deres rotasjonsakse (fig. 2) og hvis tverrsnitt utgjøres av to halvsirkler (fig. 4 - XX). Rotoren har ikke endeplater, slik at det er mulig for.luften å passere gjennom den'fra dens ene ende (fig. 4), idet rotoren når den befinner seg i horisontalstilling vender mot vinden med bare en sirkelformet flate (fig. 4).Til rotoren hører også et fundament (C,D) som muliggjør at den roterer vertikalt (fig. 1 og 2), horisontalt (fig. 3. og 4) og i alle stillinger derimellom, samtidig som den følger vindretningen.The wind screw is a wind rotor that is characterized by rotating both when the rotor axis is perpendicular to the wind (fig. 1 and 2) and when it is in the wind direction (fig. 3 and 4). It also works with unchanged power in all positions between the vertical position (Figs. 1 and 2) and the horizontal position (Figs. 3 and 4) and always faces the same surfaces towards the wind regardless of the position of the rotor axis (B). The rotor blades have a somewhat dome-shaped surface (Figs. 1 and 3). These factors have solved the difficulties of making one and the same rotor efficient both in low wind speeds (Figs. 1 and 2) and in storms (Figs. 3 and 4). The rotor consists of two wings which are rotated 180 ° helically about their axis of rotation (fig. 2) and whose cross-section consists of two semicircles (fig. 4 - XX). The rotor does not have end plates, so that it is possible for the air to pass through it from one end of it (Fig. 4), the rotor when in the horizontal position facing the wind with only a circular surface (Fig. 4). The rotor also includes a foundation (C, D) which enables it to rotate vertically (Figs. 1 and 2), horizontally (Figs. 3 and 4) and in all positions in between, at the same time as it follows the wind direction.
Description
Foreliggende oppfinnelse angår en vindrotor-anordning for energiproduksjon under spesielt krevende forhold, der vindhastigheten kan ha betydelige variasjoner, som f.eks. The present invention relates to a wind rotor device for energy production under particularly demanding conditions, where the wind speed can have significant variations, such as e.g.
på Grønland og i Sahara, der konvensjonelle vindroterer har vist seg alt for uholdbare. Forsterkning av slike vind-rotorer gjør dem uhensiktsmessig tunge. Vindskrue-rotoren fungerer ved vindhastigheter fra 3 m/s og oppover (fig. 1 og 2), men tåler også vindhastighter opp til 180 m/s (fig. 3 og 4). Den er konstruert til å fungere selv ved sand-stormer som forekommer daglig i Sahara med vindhastigheter opp til ca.85 m/s. På grunn av sin enkle konstruksjon er vindskruerotoren anvendelig selv ved meget lave temperaturer, der f.eks. hydraulisk kraftoverføring ikke kan benyttes. in Greenland and in the Sahara, where conventional wind turbines have proven far too unsustainable. Reinforcement of such wind rotors makes them unnecessarily heavy. The wind screw rotor works at wind speeds of 3 m/s and upwards (fig. 1 and 2), but can also withstand wind gusts up to 180 m/s (fig. 3 and 4). It is designed to function even during sandstorms that occur daily in the Sahara with wind speeds of up to approx. 85 m/s. Due to its simple construction, the wind screw rotor can be used even at very low temperatures, where e.g. hydraulic power transmission cannot be used.
Heller ikke høye temperaturer utgjør noe hinder for konstruksjonens funksjon. Nor do high temperatures pose any obstacle to the construction's function.
Vindrotoranordningen er i første rekke beregnet for produk-sjon av forholdsvis små mengder elektrisk energi under vanskelige forhold der bruk av store og energikrevende an-legg er uøkonomisk. Vindskruerotorens konstruksjon med-fører at den roterer under alle forhold og derved fyller sin oppgave som energi-giver, idet den roterer selv under beveg-else mellom loddrett (fig. 1 og 2) og vannrett (fig. 3 og 4) stilling. The wind rotor arrangement is primarily intended for the production of relatively small amounts of electrical energy under difficult conditions where the use of large and energy-demanding installations is uneconomical. The construction of the propeller rotor means that it rotates under all conditions and thereby fulfills its task as an energy provider, as it rotates even during movement between vertical (fig. 1 and 2) and horizontal (fig. 3 and 4) positions.
Følgende patenter vedrører og tangerer konstruksjonen:The following patents relate to and are tangential to the construction:
US Patent 4-112.311.US Patent 4-112,311.
Svensk Patent 65.940Swedish Patent 65,940
Tysk Patent 2.540.757.German Patent 2,540,757.
Vindskruerotorens konstruksjon ligger nærmest svensk patent 65.940, men den avgjørende forskjell er at vindrotoren i henhold til oppfinnelsen også roterer når rotasjonsaksen ligger i vindretningen (fig. 3 og 4). Den er en forbedring og videreutvikling av rotorer, der samme vinge-ide er benyttet. Denne rotor er utført uten endeplater. Rotorvingene kan tenkes fremstilt ved at et rør av stivt material er vridd 180° om en akse slik at det fremstår en skrueform (fig. 2). Deretter deles røret i lengden vinkelrett på aksen om hvilken den er vridd. Etter delingen har hvert tverrsnitt av røret to like store halvsirkler (fig. ,<x>2). The wind screw rotor's construction is closest to Swedish patent 65,940, but the decisive difference is that, according to the invention, the wind rotor also rotates when the axis of rotation lies in the direction of the wind (fig. 3 and 4). It is an improvement and further development of rotors, where the same wing idea is used. This rotor is made without end plates. The rotor blades can be thought of as being made by twisting a tube of rigid material 180° around an axis so that it appears in a screw shape (fig. 2). The pipe is then split lengthwise perpendicular to the axis around which it is twisted. After the division, each cross-section of the pipe has two semicircles of equal size (fig. ,<x>2).
Vindskruerotoren roterer i vertikalstilling (fig. 1 og 2)The propeller rotor rotates in a vertical position (fig. 1 and 2)
og beveges trinnløst til horisontalstilling (fig.3) i vindretningen under uavbrudt rotasjon. and is moved continuously to a horizontal position (fig.3) in the direction of the wind during continuous rotation.
I horisontalstilling utgjør den side som vender mot vinden en sirkelformel flate (fig. 4) som utnytter vindstyrken med så godt som hele overflaten. I vertikalstilling (fig. 1 og 2) har rotoren alltid enten en større (fig. 1) eller to mindre konkave flater vendt vekselvis mot vinden, slik at den konkave flate som vender mot vinden alltid er tilnærmet like stor. Også den konvekse flate som vender mot vinden arbeider på grunn av en åpning i midten av rotoren. ' Tverr-snittet av rotoren viser nemlig at de to halvsirkelformede deler er fortsatt i forhold til hverandre (fig. 4, X^,X2) slik at det dannes en åpning der luften kan passere. Rotorens to vinger er vridd 180° i forhold til hverandre sett nedenfra og oppover og mot rotasjonsretningen (fig.2). Dette medfører at en større del av vindstyrken konsentreres til den nedre del av rotoren enn til dens øvre del, hvilket øker konstruksjonens holdbarhet og selv under belastning er rotorens hastighet ca. 1,2 ganger vindens hastighet. In a horizontal position, the side facing the wind forms a circular surface (fig. 4) which utilizes the wind force with almost the entire surface. In the vertical position (fig. 1 and 2), the rotor always has either one larger (fig. 1) or two smaller concave surfaces facing the wind alternately, so that the concave surface facing the wind is always approximately the same size. Also the convex surface facing the wind works due to an opening in the middle of the rotor. The cross-section of the rotor shows that the two semi-circular parts are still in relation to each other (fig. 4, X^,X2) so that an opening is formed through which the air can pass. The rotor's two blades are twisted 180° in relation to each other seen from below and upwards and against the direction of rotation (fig.2). This means that a larger part of the wind force is concentrated to the lower part of the rotor than to its upper part, which increases the durability of the construction and even under load, the speed of the rotor is approx. 1.2 times the speed of the wind.
Vindskruerotoren holdes i sin vertikalstilling av en fjær som er innebygget i tverraksen (A) for fundamentet (C). The wind screw rotor is held in its vertical position by a spring built into the transverse axis (A) of the foundation (C).
Når vindstyrken øker til verdier som innebærer en farlig belastning på vingene og rotorakslen (B), dreier rotoren seg trinnløst til horisontalstilling i vindretningen (fig. When the wind strength increases to values that entail a dangerous load on the wings and rotor shaft (B), the rotor rotates continuously to a horizontal position in the direction of the wind (fig.
3 og 4). Da den roterer også i denne stilling kan den utnytte også meget stor vindstyrke. Konstruksjonens fordel er de lave produksjonsomkostninger i forhold til dens effektivitet under de forhold for hvilke den er beregnet . 3 and 4). As it also rotates in this position, it can also utilize very high wind strength. The construction's advantage is the low production costs in relation to its effectiveness under the conditions for which it is designed.
